I split some stuff out of a Sega Ages 2500 data package (the bin.pak files) and they're all compressed with a form identified as "lzs2" in the file. Is there a way to decompress this? Google isn't helping. Thanks.
That is part of the LHA compression format popular in japan and was used by iD in Doom and Quake. Try 7zip utility to open it.
Is there a command-line tool? I'm on Linux right now so I don't have the 7z utility and both the 7za tool and unlzma refuses to see it.
Yeah try using lha. If you don't have it im sure the repo of your distro has it. Its an old format after all.
Code (Text): pietro@pietro-laptop:~/sa2500pakfile/f_extracted/test$ lha x test.tm2 LHa: Fatal error: Unknown level header pietro@pietro-laptop:~/sa2500pakfile/f_extracted/test$ lha x2 test.tm2 LHa: Fatal error: Unknown level header :/
Damn, I was checking wikipedia and it says The link is in japanese, something tells me that this is an encrypted compression but don't take my word on this.
I don't understand that page, and it looks like the lha program expects something different? Also some of these files extract to tm2 files but the Linux tools for them are gone (or their source code was pulled)?
If you're on a Debian-based distro, you may want to install p7zip-full to open 7Z-compressed files (and variants) via file-roller.
I had that, but installing the other packages in the p7zip range turned up nothing in file-roller. I'm guessing this is a stream compressor like gzip and not a compressed archive format... Sample file (from Tetris Collection but I think all the other SA2500 games use lzs2 too, and there's gems in them too! I think this one is just an arcade flier for Bloxeed)
How do I view TIM2 files in Linux? I'm not getting any hits and TimTool in wine complained about not being able to open the destination directory. Treeki got the format cracked after we spent some time looking at the disassembled ELF and I just want to make sure everything is right. Thanks.
Okay, how about this: TIM2 file - http://idisk.mac.com/pietro10-Public/menu_gallery_tetris_md_11.tm2 Expected - http://segaretro.org/images/e/e5/Tetris_MD_JP_Box.jpg What I got - http://I.imgur.com/gtyOB.png What Treeki got - http://dl.dropbox.com/u/4558613/tetrismd11.png We both ran Game Graphic Studio (I ran it in wine). I ran TimTool again and it appeared to do nothing other than create result.log; it didn't even tell me how to use it and what it wanted to do and I can't understand this source :| xnView also showed me an invalid palette. Does anyone at all know what's up? Thanks.
I feel clever Though all I did was open this up in Game Graphic Studio (6.1.1 - the first one that came up) and change the interlace method to BGR+I
Well that explains it: I have to reload the file from the list at the bottom after clicking those radio buttons. Thanks. Now if only there was a batch processor... When I get more disk space I can download and tear through the rest of the series. I'll post the source to the lzs2 compression when Treeki gets back to me. (I could also post the program to rip apart the BIN.PAK file in Tetris Collection but apparently the format is different for some of the earlier/later games...)
Maybe I should put this into its own thread but the Fantasy Zone Complete Collection is a goldmine Manuals and arcade flyers for every Fantasy Zone game's JP, US, and EU releases (as far as Sega consoles go, at least) The entire set of planning pages for Fantasy Zone II Assorted concept art and cover art masters come and get it? (90MB, all BMP files)
Holy shit, this is some cool stuff. Thanks for taking your time to rip these! By the way, is there a way to rip the Fantasy Zone II Arcade ROMs from that disc? I know there's a pirate arcade with that game on it, so it must be really using actual ROMs and an emulator.
Well that is how the real games are done for the M2 ones (in fact, there's lots of leftover ROMs from previous entries too!) so I don't know. I'd need to prune through everything to check (again: lots of leftovers from previous entries to sort through, then I need to tie checksums to MAME sets for the arcade ones, etc.). However I'm guessing the images of the tiles before probably point to "not emulated"... but there's that System 16 Bloxeed in the Tetris Collection I need to investigate It seems like only the M2 ones have bin.pak and lzs2-compressed files. The next time I can get a hold of Treeki I'll see how we can release the decompresser; then I'll describe how to rip apart the bin.pak files (as the format seems to have changed over time, though Tetris and Fantasy Zone used the same format) EDIT DERP fz2_s16c.bg fz2_s16c.obj fz2_s16c.p00 fz2_s16c.p01 fz2_s16c.scr fz2_s16c.snd fz2_s16c.spr now to give myself a headache putting these in MAME
Speaking of leftovers, any ideas on why are there two different title logos for Mega Drive Dynamite Headdy? 0_o
Fantasy Zone 2 is in mame, is the one on the ps2 a different version? Note that both games had 317-xxxx protection chips on them, so the rom data may or may not take that into account, depending on how mame is set up.
The one in MAME is a more or less direct conversion of the Master System version, this one was explicitly made for the collection, in a way that could be actually run in modified System-16 hardware. Hence why a pirate version exists (within a multi-game board), which can be played in MAME.
Some interesting stuff in there - the Mark III covers for example - some of the folds between the backs and spines have been cleaned up (rather poorly) with MSPaint. I wonder if they grabbed this stuff from the internet.
